^^calling the tradgedy of Karbala merely "political" is a very weak remark.
Aaema (as) after Imam Hussain (as) had commemorations held in their prescence for the event of Karbala and the accounts told there were recorded. Also Mukhtar b Saqafi when once got hold of the Yazidi/Ummawi commanders and soldeirs had them give details of the crimes. These can be found in the books of the history.
